It was investigated forming of microbiocenosis of rhizosphere of soybean plants under the treatment by nitrogenfixing and phosphatemobilizing bacteria. It was shown, that the treatment of soybean seeds by nitrogenfixing and phosphatemobilizing bacteria had a substantial influence on quantity and activity of microorganisms of the main ecological-trophic groups. Introduction of nitrogenfixing and phosphatemobilizing bacteria in rhizosphere of soybean plants led to transformation of interaction between plant-hosts and their microbiocenosis. In particular, it was increased quantity of microorganisms, which uptake some root excretion, take part in processes of mineralization as well as slowing down of decomposition of humus.
